Sunda Slow Loris (Nycticebus coucang)

Was this species easy to find?

Compared to other nocturnal arboreal mammals, yes

We encountered three individuals in total on the trip, two of which were within five minutes of each other. However, as we were chiefly looking for snakes, most of the time our torches were pointing at the ground or the undergrowth on either side of the trails, rather than at the canopy, so we could have easily missed more!

I think, given recent reassessments of different slow loris species' range, this is actually a bengal slow loris (Nycticebus bengalensis)
